Cloudflare Access Not Working As Expected

I have an issue where cloudflare teams/access isn’t working.
I have it set to only allow access to sites, if the person has a OTP from a specific email domain. When I try to access the site, I get the prompt to enter an email address. I enter an email address in the domain specified by the configuration, but the email account never gets the email. I tested this once, when setting up cloudflare teams, and it worked. I haven’t touched the configuration since, but all of a sudden it is not working.
When I look at Logs\Access Requests, I can’t see anything. Gateway is blank. Admin shows that I created the policy.
Has this happened to anyone else? Is there anyplace that I can go to see what is going wrong?
Thank you for any information you can provide
